 DETAILED DESCRIPTION
A vacuum cleaner with hair-wrap cutter is herein disclosed by way of example with reference to the drawings, FIGS. 1-4. Any portion of the vacuum cleaner not specifically described herein is disclosed in U.S. Pat. No. 6,256,833, which is incorporated herein by reference in its entirety. The hair-wrap cutter according to the invention is shown and described in the context of an upright vacuum cleaner, but the hair-wrap cutter according to the invention is similarly applicable in other forms of vacuum cleaners having a rotational agitator, such as attachments for upright or canister vacuums and hand-held vacuum cleaners. The hair-wrap cutter according to the invention is further applicable to a deep cleaning machine having a rotational agitator such as disclosed in commonly owned U.S. Pat. No. 6,167,587, which is incorporated by reference in its entirety.
With reference to FIGS. 1 and 2, an upright vacuum cleaner 10 is illustrated and includes a handle assembly 12 pivotally connected to a base module 14. More specifically, the handle assembly 12 includes an upper end 16 including a hand grip 20 and a lower end 18 including an arcuate motor and lamp housing 22. Between the upper end 16 and lower end 18 is mounted a soft collection bag 24. The base module 14 includes a front end housing an agitation brush 26 and a rear end including a pivotal connection to the arcuate motor and lamp housing 22 of the handle assembly 12. The bag 24 is porous and exhausts air that flows to the bag 24. Housed within the bag 24 is a filter bag (not shown) that captures dirt and debris from the air that enters the filter bag in conventional fashion. The invention also contemplates a hard impervious bag housing and a filter bag mounted within the hard impervious bag housing for a clean air system as, for example, disclosed in the Jailor U.S. Pat. No. 5,544,385 which is incorporated herein by reference. In the clean air system, the dirty air is drawn through the filter bag by a suction motor.
Referring now to FIGS. 2-4, the agitator brush includes a spindle that is rotatably mounted to the outer housing of the base module 14 at each end thereof in conventional fashion. The spindle has one or more rows of bristles that agitate a carpet to be cleaned. A hair-wrap cutter 210 is mounted in the base module 14 housing adjacent each end 27 of brush 26 and adjacent to the rotational mountings. The cutters 210 are positioned closely adjacent the surface of brush spindle and parallel to the axis of rotation of the brush 26 to minimize the buildup of elongate particles such as hair, thread or carpet fibers on the brush 26 and especially adjacent the brush ends 27 where such elongate particles may interfere with the rotational mounting of the brush 26 in the base module 14 housing. Hair wrap cutters 210 include a cutting edge 212 adjacent the spindle of the brush 26 to sever and break up the elongate particles. Each hair-wrap cutter 210 is mounted to the base module 14 by a fastener 214 such as a screw received in an integrally molded boss 216 of the base module 14 housing.
A third hair-wrap cutter 220 is mounted to the bottom shell 88 of base module 14 in like fashion, with a pair of fasteners 224 mounting the cutter 220 to an integrally molded boss 226. Housing 22 houses a drive motor (not shown) having a motor shaft extending from housing 22 and mounting a spindle 168 for mounting and driving a drive belt 74 (shown in phantom in FIG. 2). Cutter 220 includes a cutting edge 222 positioned adjacent to spindle 168. Belt 74 is further received in groove 92 of rotating brush 26. Hair wrap cutter 220 is mounted closely adjacent spindle 168 and between the two portions of belt 74 extending from spindle 168 toward brush 26 to avoid interference with the operation of belt 74 on spindle 168. Elongate particles carried through secondary air passageway 56 adjacent belt 74 are prevented from building up on spindle 168. Elongate particles picked up by the brush 26 also tend to be carried by the belt 74 to the spindle 168. Such elongate particles have a tendency to interfere with or dislodge belt 74 from spindle 168. Cutting edge 222 of cutter 220 cuts the elongate particles from the spindle 168 and prevents buildup to reduce such interference by elongate particles with the operation of the belt 74.
While particular embodiments of the invention have been shown, it will be understood that the invention is not limited thereto. For example, the invention can applied to any vacuum cleaner that has a rotatably driven agitator, including a canister vacuum, a hand held vacuum cleaner or an upright vacuum cleaner. The invention can also be used on deep cleaners or extractors of all types wherein a motor driven rotational agitator is employed. The invention can also be used on all types of agitators in addition to brushes. The invention can further be used with air turbine driven agitators as well as electrical motor driven agitators. Reasonable variation and modifications are possible without departing form the scope of the forgoing disclosure and drawings, particularly in light of the foregoing teachings, without departing from the spirit of the invention which is defined in the appended claims.
